<3 Yes it's Postgres, email should be in the profile, would love to participate.
Postgres (and later some exciting flavors like Neon) is actually the only database I plan to support, at least for right now -- MySQL and MongoDB are not even on the roadmap really.
I might make an exception for RethinkDB since I loved it so dearly.
Don't get my hopes up... I haven't used RethinkDB in ages and have fully moved to Postgres though
But also...
Don't know who is behind it -- a company named MostlyTyped (not sure if this has old RDB engineers in it), but warms my heart that the repo is still seeing commits and usage.
